Definitely the most time-consuming stage. There were more than 120 joints to lash, each one taking around 15 minutes or more to complete. The cordage used was
"artificial sinew," a material I have run across before in my buckskinning days: nylon strands coated with wax. The result has the look of real sinew, and separates
somewhat like it, but is extremely strong, with a breaking strength of about 70 pounds. An eight-ounce spool was plenty.

For each lashing, I started with a noose around the stringer, formed by passing the loose end of the sinew through an "Eskimo knot." This knot is not the
more familiar Eskimo bowline, but is an overhand knot with a figure-of-eight knot as a stopper. The noose on the left goes around the stringer.

The Eskimo knot.

Pulled tight around a section of stringer.

A typical lashing of stringer to frame. After wrapping the sinew around several time (I used seven passes), the opposite sides of the wrap are pulled together
and tied off.

Lashing the gunwales to the bow was slightly different.

And on it goes...

Lashing the stringers to bow and stern frames required a different method, the "X" lashing. Here the sinew was wrapped around the port and starboard stringers
and again tightened by knotting the middle of the two rows.
